Application May 12, 1949,Serial No. 92,899 2.- Claims. .(CI. 26 62) My invention relatesgenerally to tenter clips i4 is pivoted to the arms 12. The clamp [4 hasand specifically to tenter clips having both a clamp and pins forholding fabrics.

It is among the objects of my invention to provide a tenter clip thatwill operate properly in a tenterframe with either woven or knittedfrabrics.

It is yet a further object of my invention to provide a tenter clipwhich will positively hold either knitted or woven fabrics, so that theymay be stretched to the proper size.

It is another object of my invention to eliminate costly changeover oftentering machines from the pin type to the clip type, or vice versa.

Still another object of my invention is to permit rapid and precisetransport of fabrics of all kinds and varieties through a tenteringmachine, whereby they may be precisely sized.

Still a further object of my invention is to provide a tenter clip thatwill make all tentering machines universal in their application tofabrics, without the substitution of specially constructed clips usuallyattendant upon the operation with each differing type of fabric.

And still another object of my invention is to provide an accessorytenter clip of the pin type that may be attached to a clamp type tenterclip;

Among the other objects of my invention is to provide a tenter clip thatis simple in form, relatively inexpensive, durable and easy to use andattach.

These objects and advantages, as well as many other objects andadvantages, may be attained from the device illustrated in the drawings,in which:

Figure 1 is a vertical side elevation of a tenter clip showing myinvention;

Figure 2 is a top plan view of my tenter clip; Figure 3 is a top planview of my tenter clips pin rack;

Figure 4 is a side elevational view showing a modified form of pin rackattached to a plate of a tenter clip; and

Figure 5 is a bottom view of the modified form of pin rack attached tothe plate of the tenter clip.

Referring now to the drawings in detail, my

combined clamp-and-pin tenter-clip presents a body member H. The bodymember has a pair of arms 12 extending upward over a plate l3 which isattached to the body member II. The plate 13 may be formed integral withthe body member I I, or separate and attached by welding, soldering, orother suitable means. A clamp ward the body member I l In operation, mycombination clamp-and-pin tenter-clip is arranged in the tentering frameon the conventional endless conveyor track that moves through a heatedchamber opposite a similar conveyor track My clip is, at all times,ready to receive a fabric, regardless of its character.

There is no need to dismantle the conveyor to substitute a clamp-typetenter-clip for a pin-type tenter-c1ip,-an operation that may mean hoursof idle machinery. 'Nor is the, reverse changeover necessary. Nor is theextravagant expedient of having two tentering machines, one for eachtype of fabric, necessary. The clamp is always available to be used withwoven materials. The pin clip is always available for use with knittedmaterials. The point of introduction of the fabric is merely changedfrom the level of the plate M to the level of the pins l9.

Figures 1, 2, and 3 show a rack it which may be attached to the bodymember II. This rack I8 may also be formed unitary with the arms l2merely by extending them.

Another way to form a rack is to provide a rack 20 which may be attachedby hinges 2| to the plate 22, as shown in Figures 4 and 5. Like theplate I3, the plate 22 may be formed integral with the body member II orseparate and attached by welding, soldering, or other suitable means.This rack 20 would normally be disposed in the position shown in Figure4 with the pins 23 disposed in a downward direction. When it is desiredto engage a fabric with the pins 23 rather than a clamp bearing on theplate 22, the rack is pivoted upward in the direction of the arrowsshown in figure 4 to the position indicated by dotted lines. Then thesupports 24 are advanced in the guides 25 and the rack 20 is therebybrought into play.

At the bottom of the body member H, and on both sides thereof, extendedportions 26 are formed with holes 21 formed therein. By means of theseholes, the tenter clip is attached to the endless conveyor track of thetentering machine.

The clamp l4 The arms I2, have attached.

It may be seen that changes such as these, as well as many otherchanges, may be made in the construction, selection, and arrangement ofthe various parts, all Within the scope of the present claims, withoutdeparting from the spirit of my invention.

I claim:

1. A tenter-clip comprising a body member, a fabric supporting plateattached thereto, a clamp pivotally attached to the body member abovethe plate and gravitationally bearing thereon, a rack positioned on thebody member above and parallel to the plane of the plate, and aplurality of pins extending upwardly from the rack.

2. A tenter-elip comprising a body member, a fabric supporting plateattached to the lower part thereof, a clamp pivotally attached to theupper part of the body member and cooperatively en-- gageable with theplate, a support attached to m 4 the upper part 01 the body member, arack positioned thereon and extending parallel to the plane of theplate, and a plurality of pins extending upwardly from the rack.
